According to specialists, a puppy can sleep up to 20 hours a day, while a healthy adult dog typically sleeps about 14 hours.
However, these hours are not accumulated consecutively but spread out. For example, they may sleep 8 hours at night and distribute the remaining 6 in naps throughout the day.
This can also vary among different breeds. A highly active animal that requires daily and prolonged exercise routines may sleep much longer to recharge energy.
Another factor that directly influences sleep cycles is their environment. In fact, when temperatures are low, dogs may sleep longer in the warmest spots of the house, while in the heat, sleep time decreases, and they spend more time drinking water.
Through this training process, it should be clear to them that this is their space, so they will recognize it and seek it out no matter if you move it from one room to another.

Sleep Cycles in Dogs and Cats
Both dogs and cats experience sleep phases similar to ours: REM (rapid eye movement) sleep and non-REM sleep.
REM Sleep: This is the phase where dreams occur. During this stage, the eyes move rapidly under the eyelids, the heart beats faster, and breathing becomes irregular.
Non-REM Sleep: This is the deep sleep phase. The body relaxes completely, breathing becomes slow and regular, and the brain deactivates.
Differences Between Dogs and Cats
Cycle Duration: Dogs tend to have shorter sleep cycles than cats and may go through more cycles in one night.
Sleep Needs: Both need sleep, but the amount varies by age, breed, health, and activity level. Puppies and kittens usually sleep more than adults.
Sleep Schedule: Both dogs and cats are crepuscular, meaning they are more active at dawn and dusk. However, their sleep schedules can adapt to their owners’.
Factors Affecting Sleep
Age: Puppies and kittens need more sleep than adults.
Breed: Some dog and cat breeds are more active and need less sleep.
Health: Illnesses and injuries can affect the quality and quantity of sleep.
Environment: A calm and safe environment promotes better sleep.
Physical Activity: Regular exercise helps them sleep better.
